Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery cells are pushed to attach to each other during pre-stacking, then the attachment efficiency is improved, but the battery cells are likely to tilt due to friction with the supporting surface
Solution Approach 1:
The patent introduces a pressing member as an intermediary component that applies controlled pressure to the battery cells during pre-stacking. This pressing member acts as a mediator between the pushing assembly and the battery cells, ensuring that the cells remain stable and do not tilt while being pushed to attach to each other. The pressing member distributes the pressure evenly and prevents direct friction between the cells and the supporting surface that would cause tilting.
Solution Approach 2:
The patent employs a telescopic member that can adjust the pressing force applied to the battery cells. By changing the pressing parameter (force) dynamically during the pre-stacking process, the system optimizes both the attachment efficiency and the stability of the battery cells. The adjustable pressing force ensures that cells are firmly held to prevent tilting while allowing smooth attachment when needed.
2Stability of the object's composition
If clamping assemblies are used to fix battery cells, then the stability during pressurization is improved, but the movement smoothness between positions deteriorates
Solution Approach 1:
The patent designs the clamping assemblies with movable clamping members that can dynamically adjust their state. The clamping members are capable of moving between a clamped position (providing stability during pressurization) and an unclamped position (allowing smooth movement during transport). This dynamic capability resolves the contradiction by enabling the system to switch between stability and ease of movement as needed.
Solution Approach 2:
The clamping assemblies are configured to preliminarily position and secure the battery cells on the tray before the pressurization process begins. This preliminary clamping action ensures that cells are properly aligned and stable when pressurization occurs, while allowing for smooth movement during the transfer between pre-stacking and pressurization positions when the clamping is temporarily released.

AI summary
Provided are a pre-stacking apparatus and battery processing equipment. The pre-stacking apparatus includes a mounting seat, a tray, a first clamping assembly, a second clamping assembly, and a pushing assembly. The second clamping assembly is disposed movably along a height direction of the battery cells, allowing the second clamping assembly to smoothly clamp the battery cells when the battery cells have moved to a pressurization position while not affecting the movement of the battery cells along with the tray otherwise, thus achieving smooth movement of the battery cells between the pre-stacking position and the pressurization position.
